Quantum controller validation

ABSTRACT

Quantum algorithms are performed via a quantum computer, by generating a quantum control pulse in a quantum controller and transmitting the quantum control pulse to a quantum processor. The quantum control pulse interacts with a qubit in the quantum processor. Within the quantum controller, a pulse processor generates a plurality of raw pulses that are modified by a front end hardware module. During the normal operation of the quantum controller, samples of the raw and/or modified pulses may be selected and saved to memory. During a design for validation (DFV) mode, the proper operation of the quantum controller is determined according to a simulation of the quantum controller and the saved samples. The DFV mode may be performed in parallel with normal operation without affecting the resources of the quantum controller.

DETAILED DESCRIPTION

Classical computers operate by storing information in the form of binary digits (“bits”) and processing those bits via binary logic gates. At any given time, each bit takes on only one of two discrete values: 0 (or “off”) and 1 (or “on”). The logical operations performed by the binary logic gates are defined by Boolean algebra and circuit behavior is governed by classical physics. In a modern classical system, the circuits for storing the bits and realizing the logical operations are usually made from electrical wires that can carry two different voltages, representing the 0 and 1 of the bit, and transistor-based logic gates that perform the Boolean logic operations.

Logical operations in classical computers are performed on fixed states. For example, at time 0 a bit is in a first state, at time 1 a logic operation is applied to the bit, and at time 2 the bit is in a second state as determined by the state at time 0 and the logic operation. The state of a bit is typically stored as a voltage (e.g., 1 V_(dc) for a “1” or 0 V_(dc) for a “0”). The logic operation typically comprises of one or more transistors.

Obviously, a classical computer with a single bit and single logic gate is of limited use, which is why modern classical computers with even modest computation power contain billions of bits and transistors. That is to say, classical computers that can solve increasingly complex problems inevitably require increasingly large numbers of bits and transistors and/or increasingly long amounts of time for carrying out the algorithms. There are, however, some problems which would require an infeasibly large number of transistors and/or infeasibly long amount of time to arrive at a solution. Such problems are referred to as intractable.

Quantum computers operate by storing information in the form of quantum bits (“qubits”) and processing those qubits via quantum gates. Unlike a bit which can only be in one state (either 0 or 1) at any given time, a qubit can be in a superposition of the two states at the same time. More precisely, a quantum bit is a system whose state lives in a two dimensional Hilbert space and is therefore described as a linear combination α|0

+β|1

, where |0

and |1

are two basis states, and α and β are complex numbers, usually called probability amplitudes, which satisfy |α|²+|β|²=1. Using this notation, when the qubit is measured, it will be 0 with probability |α|² and will be 1 with probability |β|². The basis states |0

and |1

can also be represented by two-dimensional basis vectors

$\begin{bmatrix} 1 \\ 0 \end{bmatrix}$ and $\begin{bmatrix} 0 \\ 1 \end{bmatrix},$

respectively. The qubit state may represented by

$\begin{bmatrix} \alpha \\ \beta \end{bmatrix}.$

The operations performed by the quantum gates are defined by linear algebra over Hilbert space and circuit behavior is governed by quantum physics. This extra richness in the mathematical behavior of qubits and the operations on them, enables quantum computers to solve some problems much faster than classical computers. In fact, some problems that are intractable for classical computers may become trivial for quantum computers.

Unlike a classical bit, a qubit cannot be stored as a single voltage value on a wire. Instead, a qubit is physically realized using a two-level quantum mechanical system. For example, at time 0 a qubit is described as

$\begin{bmatrix} \alpha_{1} \\ \beta_{1} \end{bmatrix},$

at time 1 a logic operation is applied to the qubit, and at time 2 the qubit is described as

$\begin{bmatrix} \alpha_{2} \\ \beta_{2} \end{bmatrix}.$

many physical implementations of qubits have been proposed and developed over the years. Some examples of qubits implementations include superconducting circuits, spin qubits, and trapped ions.

FIG. 1 illustrates an example quantum orchestration platform (QOP) in accordance with various example implementations of this disclosure. The QOP comprises a quantum programming subsystem 101, a quantum controller (QC) 103 and a quantum processor 105.

The quantum programming subsystem 101 comprises a compiler 107 that is operable to generate machine code from a high-level quantum algorithm description. The machine code comprises a series of binary vectors that represent instructions that the QC 103 can interpret and execute directly, to generate the necessary outbound quantum control pulses for the quantum algorithm, with little or no human intervention during runtime. The outbound quantum control pulses are coupled to the quantum processor 105 to execute the quantum algorithm.

In an example implementation, the quantum programming system 101 is a personal computer comprising a processor, memory, and other associated circuitry (e.g., an x86 or x64 chipset). The quantum programming subsystem 101 may be coupled to the QC 103 via an interconnect which may, for example, utilize a universal serial bus (USB), a peripheral component interconnect (PCIe) bus, wired or wireless Ethernet, or any other suitable communication protocol.

The QC 103 generates the precise series of external signals (e.g., pulses of electromagnetic waves and pulses of baseband voltage) to perform the desired logic operations to carry out the desired quantum algorithm via the quantum processor 105. For example, pulses of electromagnetic waves may be sent to one or more qubits in the quantum processor 105, thereby manipulating a state of the qubits. One or more readout resonators in the quantum processor 105 may be configured to read the state of the qubits and pass this information back to the QC 103. Depending on the quantum algorithm to be performed, outbound pulse(s) for carrying out the algorithm may be predetermined at design time and/or during runtime. The runtime determination of the pulses may require classical calculations and processing in the QC 103. This runtime analysis may be based on inbound pulses received from the quantum processor 105.

During runtime and/or upon completion of a quantum algorithm performed by the QC 103, the QC 103 may output data/results to the quantum programming subsystem 101. In an example implementation, these results may be used to generate a new quantum algorithm description for a subsequent run of the quantum algorithm and/or update the quantum algorithm description during runtime.

A QC 103 comprises one or more pulse processors 109, which may be implemented in a field programmable gate array, an application specific integrated circuit or the like. A pulse processor 109 is operable to control outbound pulses that drive a quantum element (e.g., one or more qubits and/or resonators) in the quantum processor 105. A pulse processor 109 is also operable to receive inbound pulses from a quantum element, to perform runtime analysis for example.

Quantum algorithms are performed by one or more quantum elements of the quantum processor 105 interacting with quantum control pulses. The quantum processor 105 consists of several quantum elements, e.g., qubits, resonators and flux line. A readout resonator is coupled to the qubits. The resonating frequency of a resonator depends on the qubit state. Sending an outbound pulse from the QC to the resonator would result in an inbound response back to the QC that depends on the qubit state which can be extracted by classical computation. A flux line is an element that can couple 2 qubits to perform a 2 qubit gate, or to a single qubit to manipulate its state and resonating frequency.

A quantum control pulse may be electromagnetic RF signal. The electromagnetic RF signals may be generated by upconverting a baseband or intermediate frequency (IF) analog waveform in an RF circuit 113. Alternatively, RF signals may be directly modulated. The pulse processor 109 may digitally generate and modify samples of the analog waveform.

The pulse processor 109 is configured to execute the control flow of a quantum algorithm program using one or more classical processors. The classical processors are able to perform classical computations and impact the flow of the quantum program and/or the transmitted pulses. A classical processor may be configured to control a physical layer module to generate analog waveforms and digital signaling. The pulse processor 109 may be configured to shape and modulate the analog waveforms according to control signals from the classical processor. These control signals may also depend on the previous measurements.

The digital signaling may be used as digital markers that follow the analog pulses as the analog pulses are fed through the mixed signal circuit 111 and the RF circuit 113. The digital marker may be used to: activate laboratory auxiliary measurement equipment (e.g., a scope, a photon detector), operate auxiliary equipment that is essential to execute the program, dynamically control a digital gate, and capture the inbound readout response of the qubits to send the user raw data for post processing and analysis. The dynamic control of the digital gate may enable the analog waveform transmission to the quantum element, while the QC 103 plays analog data to the quantum element to reduce noise when not playing to the element.

The analog waveforms are sent to various DAC channels 115 in a mixed signal circuit 111. The DACs 115 are operable to convert the analog waveforms from a digital representation to an analog signal that is modulated, upconverted by the RF circuit 113 and used to excite a quantum element such as a qubit in a quantum processor 105. To generate results from the quantum algorithm program, the pulse processor(s) 109 are also operable to receive, via one or more downconverters in the RF circuit 113 and ADCs 117 in the mixed signal circuit 111, readout responses from a resonator in the quantum processor 105. The classical processor(s) in the pulse processor(s) 109 are operable to perform state estimation on the readout responses to affect the program dynamic branching as well as result generation. Any classical parameter (e.g. frequency, phase, chrip rate, etc. . . . ) may also be modified according to previous measurements.

While individual components may be verified to some extent standalone, a full system validation is required to ensure that the integrated products works as a unit. Typically, the validation of one quantum controller requires the acquisition of a set of analog signals that are processed and checked against expected results. Difficulty arises because the DAC converters used for acquisition may add noise and distortion to a purely digital outbound signal. Validating a large set of quantum controllers is typically even more difficult due to the scale-up. A complex hardware switch is usually required to dynamically route such a large set of DAC outputs into a small set of scope channels.

The disclosed validation system does not require an expensive hardware switch or a manually connection of DAC outputs to limited scope channels. The disclosed validation system does not require complex data analysis to remove noise from the captured analog data. The disclosed validation system is automated, scalable and accurate to a selectable resolution of the DACs.

FIG. 2 illustrates an example QOP with QC validation using a behavior model in accordance with various example implementations of this disclosure.

An external server 201 stores a high-level quantum algorithm description 203 that is sourced for the application layer 205. The program 203 is compiled by compiler 107. The application layer 205 provides raw analog and digital waveforms to front end modules 221 of the QOP.

While the system of FIG. 1 illustrates a single quantum controller 103 and an external quantum programming subsystem 101 with a compiler 107, the system of FIG. 2 illustrates multiple quantum controllers 103-0, 103-1 . . . 103-63, each with an embedded quantum programming subsystem 101. The compiler 107 inside the embedded quantum programming subsystems 101 of quantum controller 103-0 is operable to send programming directives to all other quantum controllers 103-1 . . . 103-63 via an Ethernet connection of some other medium having similar functionality. A system with multiple quantum controllers may also locate the compiler 107 either in an external quantum programming subsystem (i.e., external computer or server).

A programming model of the controller 215 runs on an embedded programming subsystem 209 (e.g., ARM CPU). The model 215 is cycle accurate with regards to the quantum interface (ADC, DAC, and functional communication between pulse processors or controllers). The model 215 also comprises the higher level interactions between software, memory and design for validation (DFV). The DFV comprises dedicated logic that may capture digital and analog pulses at several intermediate points as well as towards the digital markers and DACs.

The hardware abstraction layer (HAL) 213 may simultaneously configure both the model 215 and a corresponding DFV controller 219. The DFV controller 219 may be implemented in an FPGA, for example. The configuration may comprise storing desired values into the model 215 and the DFV controller 219.

The model 215 and the DFV controller 219 may store data in the DDR 217 or in an external memory device (not illustrated). During or after a quantum program execution, outputs from the model 215 and the DFV controller 219 may be compared via a memory comparison to determine if the test passed or failed. The program and comparison may be rerun for different time sample values to support a scale-up. For example, if up to 8 DACs may be sampled at a time per controller 207, the same experiment may be run 8 times, while storing the data in a different memory regions, to obtain validation data for 64 DACs per controller 207.

A serializer/deserializer (SERDES) may be connected to the DFV controller 219. The DFV controller 217 may also be connected to one or more different front end modules (FEMs) 221. The FEM 221 may connect with the DFV controller via any desired communication protocol that is sufficient to steadily transmit data in the desired rate (e.g. 2 Gsps analog pulse at 16 bit representation requires 32G bit communication). For example, a 128-bit data path at 250 MHz allows a 32 Gbps, which is the bandwidth required for a single 16-bit DAC operating at 2 Gbps. Each FEM may comprise 8 DACs, and each quantum controllers 103 may comprise 8 FEMs.

The DFV controller 219 processes and packs the received data from each FEM into the DDR format before the data is written to memory 217. The DFV controller 219 may pad samples that have a smaller width than the DDR, gather data into a packet, arbitrate different packets from the different FEMs, and convert the data to the DDR controller clock frequency. It may also write different FEM sources into different memory spaces in the DDR.

To allow capturing all DACs sources, it is possible to run the same program several times and capture a different set of DACs each time. Data may be compared against the programming model every run on some of the DACs. Alternatively, the data may be stored to a different memory region every time and the comparison may be performed after all of the data is collected.

In the DFV mode, the data used within the FEM 221 is buffered 217 for a point-to-point comparison with the bit-exact behavior model 215 of the QC. Selecting a subset of the data at any given time allows the DFV mode feedback to operate over a low bandwidth. The DAC bandwidth may be, for example, 32 Gbps using 2G samples per second and a 16-bit sample size. For a DDR bandwidth of 128 Gbps, for example, up to 4 DFV data streams (4 DACs for example) may be captured without losing data. If more samples are required, the same program may be run again while sampling at different time points.

The DFV data may be stored in a preconfigured address space of the memory 217. The DFV operation may be repeated with different DACs selected across the FEMs 221 for each operation.

The DFV controller 219 may further control the bandwidth, at the point of buffering and feedback, such that only one out of several sample values, sent to a particular DAC, are actually buffered and/or fed back. Digital signaling (e.g., digital markers) may also be buffered.

The activation of this DFV mode may be controlled by the HAL 213. For example, the application 205 may send an “Start DAC DFV” opcode to compiler 107 to enable the HAL 213 to configure the QC model 215 and DFV controller 219 to capture data as a quantum program begins. The execution of this opcode may be delayed to emulate the internal delay required to compute the relevant data and bring it to the DFV controller 219. To turn off the data capture when the program finishes, a DFV disable should be inserted with the last meaningful sample.

Dedicated logic also allows software to write data to internal memories that replicates qubit responses that arrive through the ADCs. The validation platform can run experiments emulating qubit responses following readout pulses without having actual quantum hardware and without having to connect DACs to ADCs in loopback. This logic can be activated, by software or by a classical processor in real time, to select data from dedicated memories instead of the ADCs when processing the inbound pulses for state estimation.

Each quantum controller 103 comprises software components 213, hardware components 221, a behavioral model 215 and a DFV controller 219. The software components 213 are configured to selectively (and seamlessly) interact with the hardware components 221 and/or the behavioral model 215. An interaction between the software components 213 and the hardware components 221 is independent of a parallel interaction between the software components 221 and the behavioral model 215. Also, the DFV controller 219 does not affect the resources of the quantum controller 103 used for normal operation. Therefore, the same functional program may run with or without DFV without the need to recompile.

The quantum controller 103 may be debugged while executing any source code. Furthermore, the environment may be replicated with compiled code when the source code is unavailable.

FIG. 3 illustrates optional extraction points for DFV in accordance with various example implementations of this disclosure.

The FEM 221 may buffer 301, modulate 303, route 305, and filter 307 the analog waveform before the DAC 309. The FEM 221 may also buffer 310, convolve 311, delay 313 and set the polarity 315 of the digital markers prior to outputting the digital markers so processed. The convolution 311 is with a dynamic kernel.

A MUX 317 inside each FEM 221 selects which validation data to send to the DFV controller. When DFV is enabled, an associated value in the opcode may be used as a data type selector according to the following encoding:

0 Analog Raw value extracted from the buffer 301 and before modulation 303 1 Analog Modulated value after modulation 303 and before routing 305 to a DAC port 2 Analog Pre-Filters value after routing 305 to a DAC port and before filter(s) 307 3 Analog Out value after filters 307 and before feeding the DAC 309 4 Digital Markers digital vector containing digital markers following polarity set Out 315 and before being output 5 Digital Markers digital vector containing digital markers following delay 313 Delayed 6 Digital Markers digital vector containing digital markers following convolution Convoluted with a dynamic kernel 311 7 Digital Markers digital vector extracted from the buffer 310 and before Raw convolution 311 with a dynamic kernel

At 401, a plurality of raw pulses are generated by a pulse processor of the QC. The plurality of raw pulses are the basis for an interaction with one or more quantum elements in a quantum processor. The pulse processor is also able to generate a plurality of digital markers that may be associated with the plurality of pulses.

At 403, the plurality of raw pulses are modified in hardware by a front end module (FEM) of the QC. The FEM comprises a plurality of digital-to-analog converters (DACs) into which the modified pulses are routed. The DACs are operably coupled to an RF module to generate quantum control pulse that interact with one or more quantum elements.

The raw pulses may be modified via matrix multiplication, modulation, filtering and/or interpolation. The modifications may occur in one or both of the pulse processor and the FEM. During or after modification, the plurality of pulses are routed to one or more DACs.

At 405, a selection from the modified plurality of pulses is stored to memory (e.g., DDR memory or external memory, such as a hard drive). The path to the DDR memory may include intermediary buffering. For example, the pulse processor may comprise one or more application circuits that are operable to buffer the selection from the modified plurality of pulses.

The DDR memory is operable to store pulse samples that may be selected from throughout the QC. For example, the pulse samples may be taken from the modified plurality of pulses that result from the matrix multiplication, the modulation, the routing, the filtering and/or the interpolation. Each pulse of the plurality of pulses comprises a plurality of consecutive sample values that are sent to a DAC to generate an analog waveform. The sample that are stored in the memory may be consecutive samples or decimated samples, such that only one sample value out of several consecutive sample values is saved. The one or more of the generated digital markers may also be saved.

At 407, a computer processing unit (CPU) may be used to simulate the QC along with the generation and modification of the plurality of pulses.
